In your area, it would probably be better to wait until spring for transplanting. Try to keep the root ball together. Plant it at the same depth it was originally growing. Lightly firm the soil around it and water. Wait 7-10 days and then add some mulch but be sure to keep the mulch at least an inch away from the stem of the plant. It may also be helpful to trim off any blooms that may be present to reduce shock while the plant establishes itself.
